fri/.4MM JW UNITED STATES PATENT OFFICEO IMPROVEMENT IN COMBINED HARRow AND ROLLER. k

Specication forming part of Letters Patent No. 54,790, dated May 15, 1866.

To all whom t may concern:

Beit known that we, JOHN STEINER and JOHN l?. MILLER, of Harrisburg, in the county of Montgomery, in the State of Ohio, have invented a new and Improved Mode of Constructing a Combined Harrow and Roller; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

The nature of our invention consists in constructing a barrow of the usual form with a drag-bar on the under surface of the frame, and to which the barrow is attached by ajoint, that the barrow may be raised by a lever for the purpose of clearing the barrow of any obstructing material, the teeth passing through the drag-bar, and combined with the barrow is a roller and wheels.

'lo enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

The ligure represents a top View, the harrow being elevated to show the drag-bar.

B represents the barrow, which is constructed in the usual manner, with the exception of a joint formed on either side at m m with the drag-barA, upon which the barrow freely turns. The drag-bar has a series of orifices, n n n, corresponding in number to the barrow-teeth', and through which the teeth pass. The ends of the drag-bar have bearings attached to the frame, on which the ends freely move, and on the ends external to the frame are wheels D D, which support with theroller the frame and barrow when passing to and from the field.

A wheel, which Inay be dispensed with, is constructed like a caster, and is attached at o to support the point of the harroW when not in use.

At p aring is shown, to which the team is hitched.

To the post L is attached a bent lever, (not vshown in the drawing,) and the end of this lever is connected to the barrow at r by a cord or its equivalent. The use of the lever is to raise the barrow. Y

Y F F represent the frame, within which is the roller C and wheels E E, which have a common axle, the pieces i i serving as a bearing for the axle, and which pieces pass through the frame and are held in position by the pins lc k, which pass through the frame and the adj usting-holes of the pieces t" t', thus regulating the height of the frame. A part of the arm H attached to the frame is shown, which forms a support to the seat. The seat is omitted in the drawing.

To use the combined roller and barrow the wheel at 0 and wheels D D are detached. The driver being seated on the seat, when the har row becomes clogged he depresses the lever and the barrow-teeth are` drawn up through the drag-bar, thereby clearing the teeth of grass or other material, and on releasing the lever the harrowing is resumed.

When it is not desirable touse the roller with the barrow the roller is removed, the wheels E E supporting the frame.

The joint formed at the union of the dragbar and barrow should be sufficiently free to letthe barrow be thrown back onto the frame, and the drag-bar would thus be so perfectly relieved ot' weight that the supporting-wheel would not be needed at the front end of the drag-bar.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is

l. The drag-barA, constructed and arranged with reference to the harrow B, substantially as described, and for the purposes specified.

2. The combination of the barrow B, dragbar A, the wheels D D E E, and the roller C, in the manner substantially as described, and for the purposes specified.
